Yes. Open any email in the connected inbox view and you can create a new customer, opportunity, project, work order, invoice, referrer, or task directly from the thread, with the contact details, subject line, and conversation body pre-attached to the new record. The same toolbar lets you link the email to one or more existing records at any point in the thread.
The point is the workflow integrators actually run: a new homeowner emails about a Crestron upgrade, you open the message, hit "create customer", "create opportunity", and the conversation is now on both records before you have replied. Twelve weeks later, the same thread is still attached to the install, the work orders that came out of it, and the final invoice. Nothing was copy-pasted between the inbox and the CRM at any stage.
